Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
On the TP-Link TL-SG108E 1.0, a remote attacker could retrieve credentials from "SEND data" log lines where passwords are encoded in hexadecimal. This affects the 1.1.2 Build 20141017 Rel.50749 firmware.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-532

Sensitive values — secrets, tokens, session identifiers, personal data — are written into log files, so anyone with access to the logs, which is often a broad group, obtains them. It turns a routine diagnostic into a credential leak. The fix is redacting sensitive data before it is logged and tightly restricting who can read the logs.

General guidance for the sensitive information in logs class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Recommended fix Moderate confidence

TL-SG108E firmware version > 1.1.2 (e.g., 1.2.0 or later stable release)

  1. 1. Visit the official TP-Link support website (www.tp-link.com) and navigate to the TL-SG108E product support page.
  2. 2. Download the latest available firmware version for the TL-SG108E. As of the vulnerability disclosure in 2017, firmware versions subsequent to 1.1.2 should contain the fix.
  3. 3. Access the TL-SG108E web management interface using administrator credentials.
  4. 4. Navigate to the 'System' or 'Firmware Upgrade' section of the management interface.
  5. 5. Upload the downloaded firmware file and initiate the upgrade process.
  6. 6. Wait for the device to reboot and verify the firmware version has been updated.
  7. 7. After upgrading, verify that credentials are no longer visible in plaintext or hexadecimal in any log entries.
Caveat Minor: Firmware upgrades on network devices may reset configuration to defaults; backup current configuration before upgrading.

Generated from the published advisory — verify against the referenced sources before acting.

No vendor fix exists Tl Sg108e Firmware has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
